輕鋼龍骨介紹： 輕鋼龍骨是以連續(xù)熱鍍鋅板帶為原材料，經(jīng)冷彎工藝軋制而成的建筑用金屬骨架。外觀質(zhì)量輕鋼龍骨外形要平整，棱角清晰，切口不允許有影響使用的毛刺和變形。鍍鋅層不許有起皮、起瘤、脫落等缺陷。外觀質(zhì)量檢查時，應在距產(chǎn)品0.5m處光照明亮的條件下，進行目測檢查。輕鋼龍骨表面應鍍鋅防銹，其雙面鍍鋅量：優(yōu)等品不小于120g/m*m。 Light steel keel is a kind of metal framework for construction, which is made of high-quality continuous hot-dip galvanized sheet and rolled by cold bending process. Appearance quality: the light steel keel shall be smooth in shape, with clear edges and corners, and no burr or deformation affecting the use of the cut is allowed. The zinc coating shall be free of defects such as peeling, nodulation and falling off. During appearance quality inspection, visual inspection shall be carried out under the condition of bright light at 0.5m away from the product. The surface of light steel keel shall be galvanized and rustproof, and the amount of double-sided galvanizing shall be no less than 120g / m * m for superior products. 輕鋼龍骨質(zhì)量好壞決定性因素： 1、鋼帶； 2、輕鋼龍骨成型設備； 3、輕鋼龍骨鋼帶的厚度偏差大?。? 4、輕鋼龍骨雙面鍍鋅量； 5、外觀質(zhì)量； 6、龍骨廠家的精細管理。 The decisive factors of light steel keel quality are as follows: 1. High quality steel strip with high quality; 2. Light steel keel forming equipment; 3. Thickness deviation of light steel keel and steel strip; 4. Galvanized quantity on both sides of light steel keel; 5. Appearance quality; 6. Fine management of keel manufacturers.
